How to make x2 Gamepass clicks?

Yo so i am new at scripting and i dont know where i need to put variables called clicknumber and clickcount. And i have in gui button with local script

local Player = game.Players.LocalPlayer
local PlayersClicks = Player:WaitForChild('leaderstats'):WaitForChild('Clicks')

script.Parent.MouseButton1Click:Connect(function()
	PlayersClicks.Value = PlayersClicks.Value + 1
end)

and this script

local clicknum = 1
local clickcount = 0 (unless you have datastore)
	 
 
script.Parent.MouseButton1Click:Connect(function()
	  clickcount = clickcount+clicknum
end)
	 
if [insert if you have gamepass here script] then
	    clicknum = 2
	end

I need to make gamepass for my game but i dont know how

The way you're going to want to go about doing it, is send the click to the server. Then on the server after you register it, you're going to multiply it by 2 if they have the gamepass.

So instead of your code you would do something like

local clicknum = 1
local clickcount = 0 (unless you have datastore)
 
 
script.Parent.MouseButton1Click:Connect(function()
      clickcount = clickcount+clicknum
      game:GetService("ReplicatedStorage").ClickRemote:FireServer(clickcount);
end)

Then on the server register these and multiply it by 2

game:GetService("ReplicatedStorage").ClickRemote.OnServerEvent:Connect(function(player, clickCount)
  if [player.OwnsGamepass] then
    clickCount = clickCount * 2;
  end;

  player.Stats.Clicks = player.Stats.Clicks + clickCount;
end);

Hope this helps!

local id = gamepass id
game:GetService("MarketplaceService").PromptGamePassPurchaseFinished:Connect(function(plr,ido,purchased)
    if purchased and ido == id then
        clicknum = 2
    end
end)

wait(5)

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(char)
        if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(game.Players[char.Name].UserId, id) then
            clicknum = 2
        end
    end)
end)

Put this at the very begining of your code, the top function is called when the player buys a gamepass in the game and the bottom one is called if the player has the gamepass
